At present, a low-conductivity cooling liquid is mostly used as a cooling medium in a fuel cell system, and any fluid contacted with the membrane electrode should not cause potential damage to the membrane electrode, including positive ions, negative ions and particulate pollutants. Since coolant fluid is subject to erosion and wear of the piping and contact parts during circulation of the fuel cell system, and the superposition of the initially existing contaminants of the piping and other parts, additional anions and cations and particulate contaminants are generated in the system, it is very important to install a deionizing filter in the coolant circulation loop to reduce the conductivity and contaminants in the coolant.
The existing deionizers need to remove inlet and outlet pipelines of antifreeze fluid firstly after the service life expires or when the existing deionizers need to be overhauled, then the whole deionizer assembly is replaced or overhauled, so that the maintenance and overhauling time cost and the part cost are overhigh, meanwhile, when the deionizers reach the designed service life, the coolant can cause the dangerous working condition of a fuel cell engine due to the fact that the coolant conductivity is caused by the lack of ion purification effect, at the moment, the fuel cell automobile has to be stopped for overhauling, in view of the fact that the existing fuel cell automobile is still in an demonstration operation stage, maintenance sites are fewer, huge time and money waste can be caused once the automobile is stopped for overhauling or is anchored, and meanwhile, the antifreeze fluid as a slightly toxic solution is unfavorable for environmental protection and the health of operators; from the structural analysis of products, when the deionization filter is generally filled with ion adsorption resin in a cylindrical plastic shell, as the ion adsorption resin is tightly packed, the flow resistance of the product is high, and only a simple stainless steel screen cloth is arranged at a cooling liquid inlet and outlet to intercept particles, the product does not have the technical capability of deep filtration, so that the pollution-receiving capacity is low, and the stainless steel screen cloth is easily blocked by pollutants, so that the flow resistance is increased, and further, the ion purification efficiency is reduced.
